I think a lot of people would use it because movecraft sound effects and sound itself is pretty loud especially with machine guns.
Most people just disable their volume during sieges because of the loud sounds so I think that this would be nice.

You can do /togglepack to switch off the resource pack.

Obtaining the guns textures would be downloading the pack via /resourcepack and then messing with the resource pack to only have fun textures.

I can do this on my spare time

Ijust just remove the sound effects from the pack
